Specification of Letters Patent.

Patented Apr. 8, 1919.

Application filed July 18, 1918. Serial No. 245,545.

To all whom it may concern:

Be it known that 1, WILLIAM C. Lone, citizen of the United States ofAmerica, residing at Gordon, in the county of Butler and State ofKansas, have invented certain new and useful Improvements inOil-Burners, of which the following is a specification, reference beinghad therein to the accompanying drawing.

This invention relates to an oil burner and has for its principalobjectthe production of a burner which is so arranged as to spread theflame for constituting a large heating area when the device is inoperation.

Another object of this invention is the production of an oil burnerwherein a bell is mounted upon the casing and arranged so as to spreadthe flame issuing from the casing.

A still further object of this invention is the production of an oilburner which has an inner tube extending into the casing for injectingoil thereinto, while another tube is connected to one side of the casingfor injecting steam thereinto so as to allow the oil and steam to mixwhich will produce a combustible gas and supported by the injection ofair into the inner end of the casing.

With these and other objects in view this invention consists in generalof certain novel combinations, constructions and arrangements of partsas will be hereinafter fully described and claimed.

In the accompanying drawings:

Figure 1 is a top plan view of burner.

Fig. 2 is a side elevation of the oil burner.

Fig. 3 is a longitudinal section through the oil burner.

Fig. 4c is an enlarged section taken on the line a l, of Fig. 2.

Fig. 5 is a transverse section through the oil burner taken on the line5-5, of Fig. 2, looking in the direction of the arrows.

Fig. 6 is a detail perspective view of the oil tube.

Referring to the accompanying drawings by numerals, it will be seen thatthe casing 1 is elongated and is preferably cylindrical in cross sectionas shown in Fig. 5, although of course it is obvious that the same maybe of any desired shape without departing from the spirit of theinvention. This casing 1 is internally'threaded at its forward toreceive the exthe oil ternally-threaded collar 3 of the bell 4. Thisbell 4 is flared and is carried at the forward end of the casing 1 so asto constitute a flame spreader for the oil burner when the same is inuse.

The cap 5 is threaded upon the inner end of the casing 1, as shown at 6,and this cap 5 is provided with an integral, elongated collar 7 as shownclearly in Figs. 3 and 4c. This collar 7 is internally threaded asindicated at 8 and projects for distances beyond the inner and outersurfaces of the cap 5. It will, therefore, be seen that by positioningthe cap 5 upon the inner end of the casing 1, this inner end will beclosed although the forward end of the casing will be open.

The inner oil tube 9 has its threaded end 10 screwed into engagementwith the collar 7 and this oil tube 9 projects for a considerabledistance within the casing 1 as shown in Fig. 3. It will be noted,however, that this inner oil tube 9 is comparatively small so astopermit free passage space along the side thereof, while the free endof this inner oil tube 9 terminates at a distance from the bell l of theoil burner. The short pipe 11 is threaded into engagement with the outerend of the collar 7 and this short pipe 11 is adapted to receive oilfrom any suitable source of supply for conveying this oil to, the tube9, and thence permitting the oil to be discharged into the easing 1adjacent the forward end thereof.

The casing 1 is provided with an annular flange 12 formed upon one sidethereof and communicating with the interior of the easing, as shown inFig. 4. This flange 12 is internally threaded as shown at 13 so as topermit the" supply pipe 14 to be threaded into engagement therewith.This supply pipe 14: is adapted to be connected to any suitable sourceof supply for conveying steam into the casing at a point adjacent theinner end thereof and in alinement with'the oil tube 9 adjacent itsinner end. It will also be noted that the casing 1 is provided with athimble 15 having an opening v16 formed therein. and communicating withthe interior of the casing. This thimble 15 is formed upon the casing ata point adjacent its inner end and contiguous to'the cap 5 when the capis mounted upon the inner end of the casing 1.

When this oil burner is in use it is first assembled by screwing thebell 4 upon the forward end of the casing 1 and the cap upon the innerend thereof. At the time the cap is screwed upon the inner end of thecasing it is carrying the oil tube-9 as hereinbefore specified, and thenthe short pipe 11 is screwed into engagement with the cap, after whichthe supply pipe 14 is screwed into engagement with the flange 12. Theoil injected into the casing through the pipe 11 and tube 9 will bedischarged at the forward end of the pipe into the casing at its forwardend. The steam injected into the casing by being admitted through thesupply pipe 14 will strike upon the tube 9 adj acent its inner end andwill aid in the heating of this tube for the vaporizing of the oil asthe same passes from the forward end thereof. It will also be noted thatthe force of the steam and oil within the casing by being discharged atthe forward end thereof will constitute a suction at the inner end ofthe casing, thereby causing air to be drawn through the opening 16 intothe casing, thus causing the mixture of the vaporized oil, steam and airto produce a highly combustible substance which is ignited at theforward end of the casing. As the flame issues from the forward end ofthe casing, it will be directed by the flared bell 4 over an enlargedarea which is to be heated, while the air openings 17 formed in the bellare arranged adjacent the sleeve 3 of this bell thereby causing thesuction produced by the direction of the flame to be relieved by thepassing of air in behind the flame adjacent the outer end of the casing.

It is, of course, obvious that this oil burner may be used in quitea-number of ways, such, for instance, as in connection with a boiler byplacing the burner in a fire box, or when drilling wells, or for variousother purpose, for under all conditions it will produce an enlargedflame having intensified heat which because of the arrangement of theintake portions will cause the perfect combustion of the differentelements injected into the casing. I

It is not intended to limit the construction of this'device to thespecific form herein shown, for it is intended to modify the structurein accordancewith the scope of the invention as claimed.

What is claimed is V 1. In an oil burner of the class described, thecombination of a casing having an internally-threaded forward end, meansfor in- Gopies of this patent may be obtained for five cents each, byaddressing the Commissioner jecting a combustible substance into saidcasing, a comparatively large flared bell having a reducedexternally-threaded sleeve formed thereon, said sleeve screwed into saidcasing at its forward end, and said bell extending beyond the outer faceof said casing and having a formed adjacent to but beyond said sleeveand beyond said casing, whereby the flame passing from said casing willbe spread by said bell, while said openings will relieve the vacuumwithin the bell adjacent said sleeve.

2. In an oil burner of the class described, the combination of a casing,a cap threaded upon the inner end of said casing, said cap having aninternally-threaded collar projecting forwardly and rearwardly its sidefaces, an inner oil tube threaded at its inner end into the forwardlyextending end of said collar, a supply pipe screwed into the saidrearwardly extending portion of said collar, means for injecting air andsteam into said casing, and means on the outer end of the casing forspreading the flame.

3. In'an oil burner of the class described, the combination of a casingof the same diameter throughout its length, a cap on the inner end ofsaid casing and provided with a rearwardly extending and a forwardlyextending internally-threaded collar, an oil plurality of air openingspipe threaded into said forwardly extending portion of the collar, apipe threaded into the rearwardly extending portion of the collar, asteam pipe connected to the casing in alinement with and opening at itsinner end directly upon the side of said oil pipe whereby steam issuingfrom said steam pipe will be discharged directly upon said oil pipe, athimble formed upon one side of said casing and opening directly uponthe side of said oil pipe, and an enlarged bell having a reducedthreaded sleeve, the sleeve threaded into the outer end of said casingand the bell of greater diameter than the casing and extending aconsiderable distance beyond the outer face of the same, said bellhaving a plurality of air openings formed outside of the collar andbeyond the outer end of the casing, whereby the flame passing from saidcasing will be spread by said bell, while said openings will relieve thevacuum within the bell by allowing air to enter directly the bell fromthe outer atmosphere.

In testimony whereof I hereunto aflix my signature.
